Eine Dosiereinrichtung 1 zum Zuführen von Druckfarbe zu einem Farbwerk einer Rotationsdruckmaschine weist beispielsweise eine Farbwalze, z. B. eine Rasterwalze 2 und einen mit einer Rakeleinrichtung 3 versehenen Farbkasten 4 auf.
Dieser Farbkasten 4 ist an seiner oben liegenden Seite offen ausgebildet oder zumindest mit einer Öffnung 6 zur Zufuhr von Druckfarbe versehen.
Dem Farbkasten 4 ist eine Zufuhrvorrichtung 7 zum Zuführen von Druckfarbe zugeordnet. Diese Zufuhrvorrichtung 7 besteht im wesentlichen aus einer Traverse 8, einem als Spindelhubmotor 9 ausgebildeten Schraubengetriebe und einer Aufnahme für eine Druckfarbenkartusche 11.
Diese Druckfarbenkartusche 11 weist als Körper eine kreiszylinderförmige Hülse 12 auf, die stirnseitig mit einem Deckel 13 verschlossen ist. Dieser Deckel 13 ist mit einer Austrlttsöffnung 14 versehen. Diese Austrittsöffnung 14 kann beispielsweise in einem zentralen Befestigungsgewinde 16 integriert sein, welches zentrisch in dem stirnseitigen Deckel 13 angeordnet ist. An ihrer zweiten Stirnseite ist die Druckfarbenkartusche mit einer als Kolben wirkenden Scheibe 17 abgedeckt. Diese Scheibe 17 ist innerhalb der Hülse 12 verschiebbar. Hülse 12, Deckel 13 und Scheibe 17 bilden einen Speicher für Druckfarbe.A metering device 1 for supplying printing ink to an inking unit of a rotary printing press has, for example, an inking roller, e.g. B. an anilox roller 2 and a provided with a doctor device 3 ink fountain 4.
This ink fountain 4 is open on its upper side or at least provided with an opening 6 for supplying printing ink.
The ink fountain 4 is a feed device 7 for Assigned ink supply. This feed device 7 essentially consists of a crossbeam 8, a screw gear designed as a screw jack motor 9 and a receptacle for an ink cartridge 11.
This ink cartridge 11 has as a body a circular cylindrical sleeve 12 which is closed at the end with a cover 13. This cover 13 is provided with an outlet opening 14. This outlet opening 14 can, for example, be integrated in a central fastening thread 16, which is arranged centrally in the end cover 13. On its second end face, the ink cartridge is covered with a disk 17 acting as a piston. This disc 17 is displaceable within the sleeve 12. Sleeve 12, cover 13 and disc 17 form a storage for printing ink.

Die Traverse 8 ist achsparallel zur Rasterwalze 2 zwischen Seitengestellen 18, 19 der Rotationsdruckmaschine angeordnet. Mittels eines Drehgelenkes 21 ist die Traverse 8 zumindest in einer Ebene schwenkbar mit einem Seitengestell 18 verbunden. Im vorliegenden Ausführungsbeispiel ist die Traverse 8 horizontal aus den Seitengestellen 18, 19 herausschwenkbar angeordnet. Die Traverse 8 kann aber auch in Abhängigkeit von der Anordnung des Farbkastens 4 in verschiedene Richtungen, z. B. vertikal schwenkbar angeordnet sein.The crossbeam 8 is arranged axially parallel to the anilox roller 2 between side frames 18, 19 of the rotary printing press. The crossmember 8 is pivotally connected to a side frame 18 at least in one plane by means of a swivel joint 21. In the present exemplary embodiment, the crossmember 8 is arranged so that it can be swung out horizontally from the side frames 18, 19. The traverse 8 can also, depending on the arrangement of the ink fountain 4 in different directions, for. B. vertically pivoted.

Die Traverse 8 ist im Querschnitt U-förmig ausgebildet. An einem ersten Ende der Traverse 8 ist innenliegend der Spindelhubmotor 9 befestigt, so daß sich dessen Gewindespindel 22 parallel zur Traverse 8 erstreckt.The crossmember 8 is U-shaped in cross section. At a first end of the crossmember 8, the spindle lifting motor 9 is fastened on the inside, so that its threaded spindle 22 extends parallel to the crossmember 8.

An einem ersten Ende der Gewindespindel 22 ist ein Kolben 23 angeordnet. Dieser Kolben 23 ist mit seinem Durchmesser auf einen Innendurchmesser der Hülse 12 der Druckfarbenkartusche 11 angepaßt und arbeitet mit der Scheibe 17 der Druckfarbenkartusche 11 zusammen. Es ist aber auch möglich die Scheibe 17 entfallen zu lassen, so daß der Kolben 23 direkt oder unter Zwischenschaltung einer Folie auf die Druckfarbe in der Druckfarbenkartusche 11 drückt. Dazu wirkt der Kolben 23 dichtend mit einer Innenseite der Hülse 12 der Druckfarbenkartusche 11 zusammen. Die Gewindespindel 22 wird von einer nichtdargestellten Nuß in ihrer Längsrichtung bewegt. Dazu ist die mittels eines Elektromotors 24 drehbare Nuß ansonsten ortsfest bezüglich der Traverse 8 gelagert. Nuß, Gewindespindel 22 und Elektromotor 24 bilden im wesentlichen den Spindelhubmotor 9.A piston 23 is arranged at a first end of the threaded spindle 22. The diameter of this piston 23 is adapted to an inner diameter of the sleeve 12 of the ink cartridge 11 and works together with the disk 17 of the ink cartridge 11. However, it is also possible to omit the disc 17, so that the piston 23 presses the printing ink in the printing ink cartridge 11 directly or with the interposition of a film. For this purpose, the piston 23 cooperates sealingly with an inside of the sleeve 12 of the ink cartridge 11. The threaded spindle 22 is moved in its longitudinal direction by a nut, not shown. For this purpose, the nut, which can be rotated by means of an electric motor 24, is otherwise fixed in position with respect to the crossmember 8. Nut, threaded spindle 22 and electric motor 24 essentially form the screw jack motor 9.

Der Elektromotor 24 bzw. die Gewindespindel 22 des Spindelhubmotors 9 arbeitet mit einem Sensor zur Erkennung einer Position der Gewindespindel 22 direkt oder indirekt zusammen. Dazu ist im vorliegenden Ausführungsbeispiel der Elektromotor 24 beispielsweise mit einem Drehimpulsgeber versehen. Der Elektromotor 24 kann in vorteilhafter Weise als Schrittmotor ausgeführt sein.The electric motor 24 or the threaded spindle 22 of the screw jack motor 9 works directly or indirectly with a sensor for detecting a position of the threaded spindle 22. To this end, in the present exemplary embodiment, the electric motor 24 is provided, for example, with a rotary pulse generator. The electric motor 24 can advantageously be designed as a stepper motor.

An den Kolben 23 des Spindelhubmotors 9 schließt sich in axialer Richtung gesehen eine Aufnahme für die Druckfarbenkartusche 11 an. Diese Aufnahme kann im einfachsten Fall nur als ein Anschlag ausgebildet sein oder mit einer Gewindebohrung versehen sein, in die das Befestigungsgewinde der Druckfarbenkartusche einschraubbar ist. Im vorliegenden Beispiel ist ein an der Traverse 8 befestigter Auslauf 26 vorgesehen. Dieser rohrartige Auslauf 26 erstreckt sich senkrecht zur Traverse 8 verlaufend in Richtung Farbkasten 4 und ist an seinem dem Farbkasten 4 zugewandten Ende mit einer öffnung 27 versehen. An seinem zweiten Ende ist der Auslauf 26 in axialer Richtung der Rasterwalze 2 mit einer Gewindebohrung 28 zur Aufnahme der Druckfarbenkartusche 11 versehen.The piston 23 of the screw jack motor 9 is followed by a receptacle for the ink cartridge 11, viewed in the axial direction. In the simplest case, this receptacle can only be designed as a stop or can be provided with a threaded bore into which the fastening thread of the printing ink cartridge can be screwed. In the present example, an outlet 26 attached to the crossmember 8 is provided. This tubular outlet 26 extends perpendicular to the cross member 8 in the direction of the ink fountain 4 and is provided with an opening 27 at its end facing the ink fountain 4. At its second end, the outlet 26 is provided in the axial direction of the anilox roller 2 with a threaded bore 28 for receiving the ink cartridge 11.

Die Funktionsweise der erfindungsgemäßen Zufuhrvorrichtung ist folgendermaßen:The operation of the feed device according to the invention is as follows:

Zur Zufuhr von Druckfarbe in den Farbkasten 4 wird der Elektromotor 24 des Spindelhubmotors 9 betätigt. Daraufhin wird der Kolben 23 mittels der Gewindespindel 22 in Richtung Druckfarbenkartusche 11 bewegt. Der Kolben 23 gelangt in Kontakt mit der Scheibe 17 und druckt gegen diese. Die vom Kolben 23 bewegte Scheibe 17 fördert nun Druckfarbe aus der Druckfarbenkartusche 11 über den Auslauf 26 in den Farbkasten 4.To supply ink to the ink fountain 4, the electric motor 24 of the screw jack motor 9 is actuated. The piston 23 is then moved in the direction of the ink cartridge 11 by means of the threaded spindle 22. The piston 23 comes into contact with the disk 17 and presses against it. The disk 17 moved by the piston 23 now conveys printing ink from the printing ink cartridge 11 via the outlet 26 into the ink fountain 4.

Die Betätigung des Spindelhubmotores 9 kann manuell oder auch vorbestimmt dosiert erfolgen, indem eine Stellung der Gewindespindel 22 zur Dosierung einer Menge von Druckfarbe herangezogen wird.
Auch ist eine Regelung des Spindelhubmotors 9 mittels eines Füllstandssensors im Farbkasten 4 möglich.
Dieser Spindelhubmotor eignet sich besonders zur Automatisierung der Zufuhr von Druckfarbe. Neben der bereits erwähnten Regelung des Spindelhubmotores über einen Füllstandssensor ist es auch möglich, den Spindelhubmotor in Abhängigkeit einer auf den Druckfarbenverbrauch bei bestimmten Produktionsbedingungen angepaßten Druckfarbenmenge pro Zeiteinheit automatisch anzusteuern.The screw jack motor 9 can be actuated manually or in a predetermined manner by using a position of the threaded spindle 22 for metering a quantity of printing ink.
Regulation of the screw jack motor 9 by means of a fill level sensor in the ink fountain 4 is also possible.
This screw jack motor is particularly suitable for automating the supply of printing ink. In addition to the control of the screw jack motor via a fill level sensor already mentioned, it is also possible to automatically control the screw jack motor as a function of an ink quantity per unit of time adapted to the ink consumption under certain production conditions.
